The Horseshoe Calamity (PF1)

Publisher's blurb: On the frozen frontier far from civilization, a recently-disturbed shrine to an evil god has brought chaos and conflict to a community of centaurs and humans. The humans blame the centaurs’ greed for the plague of undead, and the centaurs seek a powerful magic item—starting with a single horseshoe—to put the threat to rest. Will the spirit of chaos bring all-out war or can both sides face down an ancient menace that threatens to destroy them all? The Horseshoe Calamity is a 7th-level adventure.
